Embodiment 1

[0022] The specific operation steps of green manure mixed planting to improve soil fertility and fresh grass yield in rice fields are as follows:

[0023] 1. The rice harvest time is from September 10th to October 18th, and the stubble is 25 cm when the rice is harvested;

[0024] 2. Apply 2.5 kg of urea, 25 kg of calcium phosphate, 5 kg of potassium chloride, and 0.5 kg of zinc sulfate per mu before green manure sowing, and spread evenly;

[0025] 3. Under the condition that the daily average temperature is above 17°C, mix 2.0 kg / mu of sweet potato and 0.175 kg / mu of rapeseed. The variety "Tukumangzi" was selected for the sweet potato, and the variety "Mianxinyou 12" was used for the rapeseed. In order to make the sowing evenly, use 2.0 kg of fine clay per mu, mix well with green manure seeds and 0.02 kg / mu of ammonium molybdate, and then spread evenly;

[0026] 4. For paddy fields with heavy weeds before sowing, 3 to 5 days before sowing, use 500ml of 10% glyphosate per mu...

Embodiment 2

[0034] The specific operation steps of green manure mixed sowing cultivation to improve soil fertility and fresh grass yield in paddy area are as follows:

[0035] 1. The rice harvest time is from September 13th to October 22nd, and 20 cm of stubble is left when rice is harvested;

[0036] 2. Apply 2 kg of urea, 20 kg of calcium phosphate, 4 kg of potassium chloride, and 0.5 kg of zinc sulfate per mu before green manure sowing, and spread evenly;

[0037] 3. Under the condition that the daily average temperature is above 16°C, mix 2.25 kg / mu of sweet potato and 0.2 kg / mu of rapeseed. The "Portuguese sweet potato" variety was selected for the sweet potato, and the "Zhongyou 821" variety was used for the rapeseed. In order to make the sowing evenly, use 2.0 kg of fine clay per mu, mix well with green manure seeds and 0.02 kg / mu of ammonium molybdate, and then spread evenly;

[0038] 4. For paddy fields with heavy weeds before sowing, 3 to 5 days before sowing, use 500ml of 10%...

Embodiment 3

[0046] The green manure mixed sowing cultivation method for improving soil fertility and fresh grass yield in rice fields, the specific operation steps are as follows:

[0047] 1. The rice harvest time is from September 15th to October 25th, and 30 cm of stubble is left when rice is harvested;

[0048] 2. Apply 3 kg of urea, 30 kg of calcium phosphate, 6 kg of potassium chloride, and 0.5 kg / mu of zinc sulfate before sowing green manure, and spread them evenly;

[0049] 3. Under the condition that the daily average temperature is above 15°C, mix and sow 2.5 kg / mu of sweet potato and 0.15 kg / mu of rapeseed. The variety "Tukumangzi" was selected for the sweet potato, and the variety "Mianxinyou 12" was used for the rapeseed. In order to make the sowing evenly, use 2.0 kg of fine clay per mu, mix well with green manure seeds and 0.02 kg / mu of ammonium molybdate, and then spread evenly;

[0050] 4. For paddy fields with heavy weeds before sowing, spray 500ml of 10% glyphosate per...

Abstract

The invention provides a green manure mixture sowing cultivation method capable of improving soil fertility and fresh grass yield of a rice area. The method comprises the following steps that (1) fertilization is carried out before green manure planting; (2) under the condition that daily mean temperature is above 15 DEG C, Chinese trumpet creepers and oilseed rapes are sowed in a mixed mode; (3) transverse furrows, side furrows and middle furrows are formed in a rice field, the furrows are communicated with each other, a ridge surface between every two adjacent transverse furrows is covered with soil, and subsurface water control for drought resisting should be carried out in a green manure growing period; (4) the Chinese trumpet creepers in a full-blossom period and the oilseed rapes in a full-blossom period are overturned and pressed in soil, and normal filed harrowing, fertilization and rice transplanting can be carried out after an overturn and pressing process lasts for 10 to 15 days. The leguminous Chinese trumpet creepers and the non-leguminous oilseed rapes are sowed in the mixed mode, nutrients are utilized in a mutual activation mode, light and heat conditions before rice transplanting is used fully, cultivated land resources are utilized reasonably, the cropping index is improved, rice yield of later crop is improved at the same time, rice quality is improved, land capability is increased, environment is improved, and direct promoting role is played in green manure development which springs up again in China.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to the mixed sowing cultivation technology of sweet potato and rapeseed as green manure. Background technique [0002] The main winter green manure crops in my country's double-cropping rice areas along the river and in the south of the Yangtze River are milk vetch, and the suitable time for overturning is from early flowering to full flowering. The time is in the middle and late May, during which there is a stubble vacancy of more than one month, and the light and heat are seriously wasted. In the southern region, after single-crop rice or double-crop late rice is harvested, in addition to planting wheat and rapeseed in autumn, there are vacant fields in many places that do not plant any crops in autumn and winter, resulting in land abandonment, poor green coverage of farmland in winter, and decline in the quality of cultivated land. Contents of the invention...
